I am rebuilding my engine and am wondering if it would be a good idea to replace my water pump while its so easy to get to. My truck had 170,000 on it when i pulled the engine. Has many people had their water pumps go? Let me know.

 

I would say definitely replace it, I don't know how often they fail but with 170,000 your probably pushing your luck by reusing the old one. If you've got a V6 and you have to pull everything off to replace it later you won't be happy.

 

which engine?

Mine went @ 198,000 onmy 3.0. While you're in there, replace the oil pump & seals, and adjust the vavles.

 

mine went at 140,000 miles

 

replace it! why wait for it to go another 10k and have to replace it then.
likely for a new to go 170,000 if its replaced NOW

 

Save yourself the time and go ahead and replace it. You might also look at replacing your fan clutch. Pretty sure that the fan clutch and the water pump have the same life expectancy. Tim
